Driving = Independence
Older drivers rely on their vehicles for:
� Social Activities
� Daily Responsibilities
� Vacations
� Medical Appointments

Two Important Aspects:
The Public Healt h Perspective
� SAFETY = Physical Well-Being, Preventingdeaths and injuries
� MOBILITY = Ability to get from one place toanother
Goal:To help seniors stay mobile for as long as
safely possible

The ROAD
Senior-Friendly Road Design� Safety-oriented road design has the
potential to greatly reduce death and injury
to our aging population
± intersection improvements; better
signage, lighting, and road markings; and
protected left-turn lanes
� Improvements will ultimately protect people
of all ages

Michigan Road Improvement
Demonstration Project ± Model for
Intersection Improvements
� Coordinated effort of public and private organizations
� Determined high risk intersections
� Identified needed solutions
� Evaluation yields promising results ± reduced injuries by46% and crashes by 26%
� Low-cost improvements ± pavement markings; signaltiming; left-hand turn lanes

The Left Turn!
Crashes often
occur at
intersections in
which the older person is
attempting to
make a left-hand
turn.

The VEHICLE
³Senior-friendly´ vehicles
� Better crash protection
� Effects of emerging in-vehicle technologies
on older drivers ± positive (crash avoidance
technology) and negative (distraction)
� Ensuring vehicles ³fit´ aging bodies

Crash Rate and Aging
The crash rate for older drivers is related
to physical and mental changesassociated with aging
Impaired vision
Hearing Loss Impaired joint mobility
Neurologic impairment

� Visual Search� Visualization of Missing Information
� Lower Limb Strength and Mobility
� Head-Neck Flexibility
Based on research on nearly 2000 drivers 55-96 years,seniors with a decline in any of the 8 areas were 2-5times more at-risk of being in an at-fault crash (Staplin etal, JSR 2003)
